Whey protein isolate (WPI) is a type of whey protein that has been processed to remove fat and lactose. It is the purest form of whey protein and contains the highest percentage of protein.
Isolate is more expensive than concentrate, but there are health benefits associated with consuming the isolate.
What Are Isolates?
Isolates are highly processed, and this processing removes some of the benefits that you can find in unprocessed whey. However, this form of whey has a higher percentage of protein per serving, making it very popular among bodybuilders and athletes.It is also lower in carbohydrates and fat, which helps develop lean body mass and lose weight. Whey protein isolate is created by microfiltration, which spins the whey until it is isolated.The final product contains 90% protein content or higher. This processing method is used among other types of food products to improve consistency, taste, and nutritional value.
The Benefits of Whey Protein Isolate
If you are looking for a way to increase your daily intake of protein, this form of whey is an excellent choice for a supplement because it has almost no fat or carbohydrates. It has very little lactose, so if you have problems digesting milk or milk-based products, this will be easier on your stomach.
You can buy isolate online here. Studies show that WPI does not adversely affect triglycerides, cholesterol, blood sugar, insulin, cortisol, thyroid hormones, or renal function in normal healthy adults.
However, if you are taking medication to manage these conditions, it may be best for your health to avoid using any whey supplements until you can verify with your doctor that there are no adverse interactions with the medications.
Isolates have benefits over other forms of protein supplementation because they do not contain fat or carbohydrates, making them an excellent choice for people looking to diet or cut back on either one.
They also have less lactose, which means that this form of whey will generally cause fewer stomach problems than concentrate does for people who have sensitivities.
When selecting an isolate, look for products that have been cold-filtered and micro-filtered. These processes ensure that all undenatured protein is kept in the product.
How Is It Made?
Whey protein isolate is made by first separating the whey from the curds. The whey is then filtered to remove any remaining lactose and fat. Finally, it is dried and powdered.
This process results in a product that is over 90% protein. Making whey protein isolate is a costly process, so it is more expensive than other forms of whey protein.
Whey protein isolate powder is packaged using special bagging materials to ensure maximum protection from moisture and light until the product is ready for use. If you purchase a packaged product using inferior bagging and packaging materials, the protein may be exposed to moisture and light, deteriorating its quality.
Whey protein isolate undergoes extensive testing to ensure purity specifications before being sold as a dietary supplement. Always look for products that have been tested by an independent third-party, as this is an excellent indicator of product quality because brands do not typically test their own products.
If you are looking for a purer form of whey and do not have any problems digesting milk-based products, then whey protein isolate may be the right choice for you. It has a high percentage of protein and is low in fat and carbohydrates.
It is also processed to remove lactose, making it a good choice for people who have trouble digesting milk. When selecting an isolate, look for products that have been cold-filtered and micro-filtered to ensure that all of the undenatured protein is kept in the product.
